I’ve noticed that MP1405 based boards are offered as widely as TP4056.
It says that they have protection built-in. That might be very useful for small DIY projects. Did anyone here test them. Are they as good as TP4056 based boards?
Ordered one of these today:
Only now I’ve noticed that there are two BAT- connections. What for? Also, R and G connections are for external LEDs, right? And what is the EN connection for?
Hello,
I need to know where i can buy the TP4056 as chip only.
I want to integrate it on one of my boards.
I do not need the full populate pcb as it is too big
Any link to buy outside of China ?
I am actually in Canada.
Ebay sellers do not need to apply, due to the facts that they are more expensive than the full assembled PCB.
I bought the full PCB for 0.9USD
I haven’t seen this type of board before, I like the idea of integrating charging and protection in the same board! does someone know what kind of protection does it have? over discharge only? or it also has over current protection? if so, how many amps? (I assume It doesn’t have overcharge, being a charger supposed to stop by itself, but if it has also a separate controller for protection with overcharge too, this is a great find!)
I might have some ideas. How many are you looking to buy?
On second though, I don’t have any bright ideas. I took a quick look at ebay and in the US, you can get them shipped for $0.50USD/chip in lots of 5, or$0.15USD/each for 100. Yeah, they ship from china, but that’s the source.
I believe it’s the equivalent protection IC’s that are round and on the bottom of 18650’s (more or less) example possibly 2A output (I believe for more they use more chips)
I would like to know if reverse polarity protection built in with the protection IC or if you put them in backwards will it smoke the protection IC as well
